| Abstract: | A cast iron with rare earth,nickel,chromium,copper was designed and its microstructures were observed by the light microscope;the corrosion rate of cast iron in the alkali liquor was measured using hydrometer method.The results show that,the microstructures of cast iron are refined,the pattern of graphic is modified and the alkali corrosion resistant properties are improved due to adding the rare earth. |
